Materials science is a fascinating area of research that is often at the cutting edge of science and engineering. It involves both developing new materials and improving on existing ones, and has important applications both for improving daily life and for advancing other fields of research. You can try your hand at making and testing all kinds of substances from plastic to slime.

Science Fair Project Idea
In the fairy tale of the three little pigs, the wolf huffed and puffed and blew down the first pig's straw house. But in reality, straw, tied into bales, is a viable building material that, when used properly, makes sturdy and energy-efficient buildings. Straw is a renewable resource that is available all over the world since it is the byproduct of growing grain. In this science fair project, you will test a straw bale covered with stucco to see if it's water resistant, and evaluate if it's… Read more
Science Fair Project Idea
There are currently two different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g. Saran or Glad Wrap) and polyvinyl chloride (PVC) (e.g. Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film). Which of these materials is less permeable to oxygen? When you slice an apple, the surface of the slice turns brown as the apple is oxidized. Can plastic wrap seal out oxygen and prevent the apple from browning? Which plastic wrap works best? Do… Read more
Science Fair Project Idea
It's hard to imagine a world without paper. You wouldn't have things like books, cards, comics, newspaper, construction paper, notebooks, cereal boxes, or that nice sound of shredding wrapping paper on your birthday. There was a time, though, when the only thing people had to write on were slabs of soft, squishy clay. When these slabs dried in the sun, they preserved simple ideas, but they were heavy, like carrying around a load of rocks. Not exactly easy to put in your pocket and carry around.… Read more

Here's a project for a budding architect or structural engineer. Can you make a strong, lightweight tower using only uncooked spaghetti and white glue? In this project, you'll learn about materials testing and apply what you learn to building and testing structures that are both strong and light. Read more
Science Fair Project Idea
The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more
Science Fair Project Idea
Do you ever go camping with your family and roast hot dogs and marshmallows over a campfire? If you want your campfire to burn long into the evening, what is the best wood to use? Do research on the necessary conditions/materials to sustain a fire and on the properties of different types of wood. Which properties do you think will be most important for determining how fast the wood burns? For example, how do you think density would be related to burning rate? Why? Measure the density and… Read more

If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more

Science Fair Project Idea
What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than… Read more
Science Fair Project Idea
Does adhesive tape hang tight at different temperatures? Measure the adhesive strength of tape at both low and high temperatures. To raise the temperature, we suggest using a blow dryer at both low and high heat settings. To lower the temperature, use an ice pack (try to keep condensation from forming on the tape and confounding the results). For even lower temperatures you could try "dry ice" (frozen carbon dioxide), if available. (Wear heavy gloves when handling dry ice, because it can… Read more
